Drilled 3/4" hole in F-1204D bulkhead, deburred, and installed snap bushing (step 2). Had to disconnect the fuel return line so there was room for the 90 degree drill. Reconnected fuel return line and tightened 1/4 turn after finger tight.
Steps 3 and 4 are NA if installing GTR-200 (my configuration).
